James,
Your idle problem could be the cause of the fluxuation. The first thing I
would ask is how long ago have you changed the spark plugs, cap & rotor?
If it's been a while, I would start there. If that doesn't take care of it,
I would change the oxygen sensor. It could be giving out false readings if
its going bad. I severely doubt the cam temp would even be a factor in
this situation.
